Jenkins Group Paper Highlighted in RSC Blog

August 2, 2012 by chemweb

The Jenkins Group published a paper entitled “Exploiting a Dimeric Silver Transmetallating Reagent to Synthesize Macrocyclic Tetracarbene Complexes“in Chemical Science. The paper was also highlighted in the Royal Society of Chemistry (RSC), Chemical Science blog.

The paper, co-authored by Zheng Lu, Alan Cramer and David Jenkins, showcases a general synthetic method to prepare macrocyclic tetracarbenes with first, second and third row transition metals from both sides of the periodic table, using a dimeric silver transmetallating reagent. These silver transmetallation reactions demonstrate a generalized process, wider metal variety, and higher product yields than other typical synthetic methods for preparing polydentate carbene complexes.  Their synthetic advance lifts these intriguing compounds out of the realm of curiosities and opens up avenues to their future study and application.

Professor Camden Received NSF CAREER Award

July 15, 2012 by chemweb

Jon Camden, an assistant professor of analytical chemistry at UTK, has been announced as a recipient of the CAREER award from the National Science Foundation.

CAREER award is one of “the National Science Foundation’s most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.”

Camden’s award includes a 5-year $600,000 grant to support his research and educational activities. “The CAREER recognizes the potential of our research to be transformative and to integrate our research mission with education. This award will have a major impact on our efforts and it is a privilege for which I am very grateful.” Camden said.

Funding from this award will be used to develop surface nonlinear spectroscopy as an analytical method for probing the two-photon properties of molecules, surface adsorbate structure, and ultrasensitive detection.  Camden group will pursue detailed comparisons between experiment and theory. “This work is fundamental in that it explores how molecules adsorbed on nanoparticles scatter light, and it provides much needed experiments for the benchmarking of new theoretical methods of calculating nonlinear molecular properties.” Camden added, “It also has the potential to impact a wide range of practical applications such as catalysis and renewable energy production.”

In addition to the scientific endeavor, Camden group seeks to increase the number of high-school students pursuing Science, Technology, Engineering, and Mathematics (STEM) majors in college. In collaboration with Debbie Sayers, a Chemistry Teacher at Hardin Valley Academy, Camden and his group will provide curricular enrichment to local public high-schools through the creation of ASPIRE teams (Aspiring Scientists Participating in Research and Education).  ASPIRE teams will deliver hands-on laboratory experiments to local high school classrooms once a month during the regular school year, for a total of six activities.

A Chemist in the Making

April 24, 2012 by chemweb

Someone who looks at Britta Johnson’s resume will find a number of impressive achievements, including several semesters of undergraduate research in the University of Tennessee’s Department of Chemistry.

In recognition of her research efforts, Johnson was awarded a Best Presentation prize during UT’s 2012 Exhibition of Undergraduate Research and Creative Achievement (EUReCA).
The project she presented, “Dynamics of He adsorption on
MgO(100) surfaces,” focused on theoretical studies of the bound states of He atoms that are adsorbed on the surface of an MgO crystal.

Some of Johnson’s results were published in the Journal of Physical Chemistry* in 2011, in an article titled “Pairwise Additive Model for the He-MgO(100) Interaction.” Johnson was the article’s first author.

Britta’s co-author, Robert Hinde, has been Johnson’s undergraduate research mentor.  The two have worked together since summer 2009.  “Britta has been a great student and a great collaborator,” Hinde said.  “Her research has taught us a lot about fundamental atom-surface interactions.  A better understanding of these interactions can ultimately help scientists understand in more detail how chemical catalysts work.”

Johnson joined UT as a College Scholars major with a program of study titled “Quantum Dynamics and Mathematics.” When asked how she became interested in chemistry, Johnson responded that, “I knew I wanted to at least try research and see if it was something I would want to do… my Honors Chemistry professor (Dr. Kovac) had suggested I look into doing research with Dr. Hinde, and I’ve never looked back.”

Hinde’s research area is computational and theoretical chemistry, which might not be what most people think about when they first hear the word “chemistry.”  Research projects in theoretical chemistry frequently combine topics from chemistry, physics, and mathematics, and the projects often involve the use of computer programs to solve mathematical equations or perform simulations of chemical phenomena.

“I think it is amazing that basic mathematical concepts can be used to understand and model increasingly complex chemical systems,” Johnson said.  She added that she also found writing her own computer programs to be somewhat “intimidating” at the beginning; as she persevered, however, she became more fluent in programming and started writing, from scratch, the programs that she used in order to conduct her research.

Johnson felt grateful for having Hinde as her mentor. “I could not have asked for a better research advisor; whenever I have questions, whether they be about research, classes to take, or graduate school applications, I can always go to Dr. Hinde for advice.”

Johnson grew up in Knoxville and went to Karns High School before she joined UT.  While at UT, she was named a Goldwater Scholar.  After graduating this spring, Johnson will attend the University of Wisconsin to earn a Ph.D. degree in Physical Chemistry.

*The Journal of Physical Chemistry A (Dynamics, Kinetics, Environmental Chemistry, Spectroscopy, Structure, Theory) publishes studies on dynamics, clusters, and excited states; kinetics, and spectroscopy; atmospheric, environmental, and green chemistry; and molecular structure, quantum chemistry, and general theory. Out of 121 journals in the Physical Chemistry category, The Journal of Physical Chemistry A ranks #7 in total citations with 48,355 total cites. The Journal of Physical Chemistry also ranks #4 in citations out of 32 journals in the Atomic, Molecular and Chemical Physics category.

Undergraduate Chemistry Major Receives Summer Internship

April 17, 2012 by chemweb

Chris Freye, a rising senior in the Chemistry undergraduate program, and a member of the Chancellor’s Honor Program received 2012 undergraduate summer research internship from the UT Office of Undergraduate Research.

Freye will be working in Professor Sepaniak‘s lab on a project labeled Advanced Separation Techniques Employing a Novel Means of Detection.

“I will be integrating thin layer chromatography with surface enhanced Raman spectroscopy.’ Freye said, “The goal of the project is to carry out a separation on a TLC plate, transfer the analytes from the plate to nanocomposite which would be analyzed by raman spectroscopy.”

Freye is extremely excited for receiving this internship opportunity. “I have been working for Dr. Sepaniak for the last year; however, I have had to pay attention to my school work. This summer, I will be able to fully concentrate on my project and hopefully excel.”

Freye is also very thankful that his mentor Professor Sepaniak and UT Office of Research could provide him with this great opportunity.

Undergraduate summer research internships are funded by the UT Knoxville Chancellor’s Office and Office of Research. Up to 75 interhships at $2,000 each are awarded each year to support students who will work on a research or creative project with a UT Knoxville faculty mentor during summer time.
